I asked the same question about 2 years ago...a lot of folks suggested RCBS or Redding for single stage presses, and Dillon for progressive. Most of the old timers that had a Dillon recommended starting out with a single stage press. Against my inherent tendencies to ignore good advice, and spend lots of money, I ended up with a Redding Boss press, which is probably comparable to a Rockchucker.
The Redding is a really good press, and I've never had a single issue with it. I've used RCBS and Redding dies, and even have a Hornady set for 8mm. I prefer the Redding and Hornady dies over the RCBS, but that's just me. Their all good.
After reloading for a year and a half, I finally broke down and got the Dillon 550B. I'm actually very happy that I did it that way...I'm pretty sure I would have been totally overwhelmed by the Dillon and everything it does had I never tried reloading in a single stage press. And, even though I have the Dillon, I still use the single stage to decap everything, and bang out 20 to 50 rounds of stuff for the old bolt guns, like .303, 7.7Swiss, and 8mm. It comes in handy for the small jobs.
Also, with the Dillon, there's gonna be a LOT of stuff you want...extra tool heads, stands, powder measures, the roller handle etc...all of that adds up, and the caliber conversion kits, which have the shellplates and shellholder buttons for each caliber are $35 a pop...you need one for each caliber you're gonna load, PLUS the dies.
You may end up hating reloading, too...it can be tedious and time consuming, that's for sure, which is another reason for a single stage...get in for as little up front as possible, then see how you like it.
If you do decide to go single stage, I'm sure you can find a RCBS or Redding kit for under $300, which will have all the stuff you need to get started, minus the dies. I have no experience with Lee, so I can't give you any insight to how their stuff works.
I *think* that Dillon has a version of the 550B that is single stage, but upgradeable....I don't see it on the website, but I could swear I saw it in the catalog. If I didn't hallucinate, that may be something worth exploring for you.
Good luck with whatever you choose...you'll at least end up with a larger quantity of better ammo for your $$.
