I would suggest at least a 20-ton hydraulic press. I was fortunate to find a 20-ton Nugier hydraulic press from a company that was replacing it and getting a new 40-ton air-over-hydraulic press for their maintenance department shop. I picked it up about seventeen years ago when I first finished my shop at home for $125.00. The table was bent slightly, the gauge was broken and the ram leaked terribly. I straightened the table in our press at work, repacked the ram after special ordering new packings/quad-rings for it and replaced the gauge. Total I am into it under $200.00. I was even able to talk the guy out of the arbor plates that came with it when new. I cleaned them up and deburred them after getting it home as well. I also made two new, larger arbor plates out of worn out forklift forks a few years ago.
It has worked great for the past seventeen years and I have never needed any more than the 20 ton capacity that it offers. I also like the fairly small footprint as it doesn't take up much room in my shop.

Here is one very close to the condition mine was when I bought it. It was probably about 10-15 years old when I bought it seventeen years ago. This one also looks like the table is bent a little.
Another neat feature on the Nugier that I haven't seen on very many others is the small cable operated table lift that is operated by the hand crank on the right side and the locking notched wheel on the left side. I really like that feature on mine although I have had to replace the cable several years ago.
Rather than purchase a POS cheapy press, I would keep an eye on ebay, Craigslist or your local classifieds for companies upgrading their older higher quality presses. Purchase a good one once and don't worry about when it will give you problems.
