I would say intended use is going to be the deciding factor here. If you’re going to pull the occasional pin a few times a year, then the el cheapo will work great for years. If pulling pins and bearings is something you’re doing on the regular, I’d drop some coin and get the sood stuff. I’ve got 2 pneumatic foot pumps, one enerpac and one OTC, I use the OTC the most. I’ve got 2 30 ton hollow Cat branded rams, 1 50 ton aluminum Cat, and 1 10 ton short cat ram. I’ve got several temco pancakes and a 20 ton and 1 simplex 50 ton steel ram. I don’t see a problem with the temco stuff that I’ve got, it performs well. I’ve used a few hydrafore rams and they’re good for what they cost, if they sh*t the bed, throw them away and get another. Name brands can be rebuilt and is cost effective to do so, the cheapo ones aren’t worth the time let alone the money to rebuild. The name brand stuff tends to handle more abuse than the cheap ones, which is good for field work. This is just my experience with the products. Hope you find something that works for you.
