Having a shoebox is the only way to go if you can afford it. The product is great and there customer service is the best. I had to do a major rebuild on mine, I called Tom and he walked me through the whole thing, stayed on the phone with me till it was back in service. The whole thing should have taken about 20-30 minutes but my fat fingers had trouble getting the chain back on. It took me a half an hour just to get the chian on, the rest was very easy, and Tom never once complained, kept trying to offer me suggestions to make it easier and stayed on the phone with me for 58 minutes. I was reluctant to purchase something that I would have to rebuild after 100 or so hours of use, but its mostly just swapping out an O-ring or two. It really is not a big deal at all. Really.The toughest problem is moisture if you live in an area that has any humidity. Compessing air creates moisture, and you dont want that in your tanks or gun. I used the small little inline moisture traps but still had an issue until I found a good dryer. The one I have is sold by Harbor Freight but my local Harbor Freight didn't carry it and it is not listed on their website so I got mine off Ebay. It is very simple and has 2.2lbs of dessicant inside (reusable). It also has a water trap. I run a 50ft hose off the 1st stage to a water/dirt trap, then into the big dryer, another water/dirt trap comming out of the dryer, to another 50ft hose and 2 small inline traps on top of the shoebox. No more moisture issues. If you can find the dryer at your local Harbor Freight I hear it runs about 40 bucks, which includes reusable dessicant. I paid a bit more on Ebay for mine. Here are a couple of pictures of my setup.
