I've come to a point where my $400 mastercraft boxes just won't do anymore.

I know Vidmars and Lista are GREAT boxes, but I can't afford the box and any more tools to put in it on an apprentice wage. All the inserts and other 'dense' type storage I put into the company Vidmar, so I don't need that great quality either. I'm here in Alberta, Canada so alot of the great priced mid-quality product sites I found through searching this forum won't ship to me. Craftsmen Pro seems to be the best I can get around here without getting snap-on/mac, and $1000 for a 42" roller of that quality just seems too high.

What I have found with Canadian shipping prices are CLARKE and EXCEL boxes. Both of which I've never heard of, but appear to be craftsmen/beach/mastercraft quality at about half the price.

Along with any advice on brands, and where to buy I'd REALLY like more generic advice on what to get or not get with a box.
-Is it worth it to wait and save for a Vidmar quality box?
-Do PrincessAuto/HF brands make since in the mid-term?
-How wide, and generally how much storage do you guys use?
-How heavy do you usually load yours?
-Are there specific features (other than the obvious roller bearing slides) that are important?

I get the impression that application is just as important with tool boxes as it seems to be with most other products, so here is some basic information on my use.
-I Rarely move my tool box
-The heaviest drawer so far is full of reference books,.
-Although I don't lock my box right now (Real small company) I will when I move to a larger company.
-I keep everything from my measuring tools, to my ratchets&wrenches, to my hammers
-Having some space on the top is really nice for writing/drawing/reading


Sorry to ask so many open questions, but I feel like I'm really over my head and I hope the experience and advice from all the great members of this forum will steer me toward the best decision.
