Ya, steel is hella expensive. I could could have got all of my metal at the price that dealers pay, and an I-beam frame with W6x15 beams (which I have since found out are still not big enough!) would have been upwards of $700. That's not including any labour, though I am able to have that for free. Im not sure what pricing is like in the US, but steel's really expensive right now. I ended up with a different design which isn't quite as nice as a side-loading I-beam, but still isn't an end loading one... It's very similar to the Kingswood press. Took a bit of time to do up the design and figure it all out, but I think I'm going to be happy with it. It just arrived at my house a couple of days ago, so I'll hopefully put some picks somewhere soonish. Still don't have my molds finished, or the heat system wired, so I may wait til that's all done, then do a big post, we'll see. anyways, this one, which uses box tube and flat bar still cost about $300 for just the metal (I was stoked to find the metal that cheap too, I found a place that must have purchased their last shipment just before one of the big price jumps; they sold to the public, and it was actually cheaper than the other source that sells to huge companies in the building and trades industries). I would budget at least $1200 for a pneumatic with a nice heating system. I did a lot of sourcing and think I got some pretty good prices, but when considering all the metal for the frame and cat-track, the PID, heat blanket, etc. it adds up. It could be done for less, I got pretty high-end stuff for all of it. I already have a compressor too. That's been my experience with it. You can really reduce your metal cost by doing an end-loader though, because you have supports all the way along the frame, you can use waaaayyy lighter metal... this actually makes so much difference to the required strength.
