The slippery slope has come into view! If you are gonna do any metal fab work you will need either a Cold Saw, or one of these:

This saw is amazing, when I stopped working at the fab shop, I really missed the Haberle Cold saw.
Since my shop is a much smaller scale process, I got the Makita Dry Saw when they first came out, still would like the Cold Saw, but for the space and efficiency this saw will save tons of edge cleaning and cuts with amazing precision, leaving an almost machined surface. My abrasive saw and band saw are for a few select materials like rebar and aluminum. The best part of the Makita is a fast cut, with almost no sparks. The blades aren't cheap, but I buy them on eBay when someone clears out stock. One blade lasts about a year of my normal fabrication needs, unless I cut Titanium, then they become dangerous frisbees. You just missed 2 Makita Dry Cuts on craigslist, and I almost bought them because they were so cheap.
I had been lusting after a welding positioner, but the price was off the table. I found this one on eBay, price was very reasonable:
