Ebay has a bunch of presses at any given time, totally depends on what you load and your budget, I'm able to load just about anything with 4 different ones, rcbs partner, rcbs rockchucker, Dillon 550b and mec 600jr.
Rcbs rockchucker is probably the most popular metallic press of all time, there's a good reason for that, you can load everything except 50 bmg and shotshells with it, albeit slow however.
Mec shotshell loaders are not great but they work and most are budget friendly, 600jr's will do a decent job unless you shoot often, for high volume loading get a grabber. If anyone ever offers to sell you a 9000g consider that person with suspicion, they do not have your best interests in mind!
Check with your LGS, not unusual for one that's been around a while to have boxes of old reloading equipment in the back including presses, sometimes these can be a real bargain. You'll see lots of C frame presses, these are not suitable for magnum cartridges imo, some O frame presses feel like they're going to come apart when sizing magnum cases as well, good example of that that's seen often for sale used is the rcbs junior, 30-06 is about the limit for that press.
