As far as price goes... I'm gonna wing it here... all prices are off the top of my head, but should be close.
Melamine wood - 2 uprights, 7 shelves = $120
Estreet plastics (x5) - $126
Melamine peg board - $16
Lattice Dividers and ends - $40
Vinyl edge - $10
13x13 tiles (x5) - $5
Foil tape - $7
Silicone II caulk x2 - $11
Flourescent fixtures (x5) (ebay) - $30
Flourescent bulbs (x6) (ebay) - $20
Extension cord for wiring lights - $9
Misc hardware (screws, pegs) - $10
Small trim to hide 12v wires - $6
Red LED lights - $14
12v power supply, no idea I have tons of extras, probably $10
Repti-cable (x2) - $34
I had the ReptiTemp 500r's (x2), but those usually go for about $25 each
Light timers are usually $10
So, building it from scratch would be somewhere around $528. Granted most people will already have some of the stuff you need, so it should come in under $500.
