Well I've owned both of the presses. When I started out reloading back around '94 I bought the Lyman T-Mag press in the starter kit from I believe Cabela's. It had everything I needed at the time for my 40 S&W, 44 Mag and 30-30. This is at the time the only three things I reloaded for and the turret option was a nice thought. Lyman dies have all the things you'd want...sizer, expander w/powder measure adaptor, seater and crimper. I'd set them up in the press and would leave them there until I was done reloading a batch, usually a batch of 50 or 100. This was great for things like the 40 S&W...I didn't have the money for a Dillon (still don't) and this was the next best thing. I probably loaded up around 2500 rounds of that ammo over a couple of years and it afforded me a lot of shooting back in the day, every penny helped since I was in the Air Force and didn't have much $.
Things I've noticed using the T-Mag press by Lyman. Make sure the "nut" on top of the turret is tight (and the "nut" operating the press is awake), if it comes loose the bullets could be out of round. This is caused by the ram lifting the turret slightly upon seating of a bullet. Also make sure the device on the back of the press that can be set to touch the bottom of the turret head is against it. If you've ever seen one of these presses you'll know what I'm talking about. Other than that you're all set with everything else that comes in the kit. I used the balance beam scale for way too many years and as you state they come with a electronic scale now make me jealous.
If I were to get this combo I'd also get a second manual buy someone like Hornady, Speer, Nosler or Sierra. It just gives you more options.
Now for the RCBS...love this press. I've gotten away from handguns, still shot them some, but for the most part load and shoot rifle rounds. I've also become very precise in reloading and wanted a good single stage press and looked them all over and settled on the Rockchucker. Very strong press and loads all rounds with ease, just a very smooth press. Cannot say enough about this press. I load each round as if it were to make a 400 yard shot if needed and spend a lot of time doing so. I size all the brass, clean primer pockets, check length, chamfer inside and out, through low and trickle up powder charges, seat and inspect all round for uniformity. I want to get into case mouth turning and more precision oriented things.
I guess I feel the RCBS (or other single stage) presses are more of what I'm looking for these days. I started out some twelve years ago wanting to save money (that a novel concept, how do you do that with all that stuff out there you can spend money on in the reloading realm)!!! I find myself looking at purchasing firearms not on the ease of finding factory rounds but dreaming of the load combinations I'm going to come up with to work in the rifle.
This turned out to be much longer than I intended it to be, just remember I started out with a modified TV stand and now have a huge bench and several different calibers and a very set way of doing things. Your on the right track reading, I can't stress this enough to new reloader I have ask me questions. Make sure you look down the road a few years and see what direction you intend to take things. If I were to get a progressive press I'd buy a Dillon Square Deal. Don't need the 550 because I'm not going to reload rifle that way. I'd only load things like my 40 S&W or 357 Mag.
I was in Cabelas the other day and over heard a person asking if it was worth the cost to get into reloading. I replied...don't do it because before you know it you'll be 4,5,10 cartridges into the game, you'll want the newest gear your wife will never see you because you'll be either at the reloading store, reloading bench or at the range trying to save money over those $13 boxes of cheap ammo at walmart. I does sound nice doesn't it. :twisted:
All right probably way too much here, what ever you do spend your money wisely.
