I found http://www.amaxit.com/ and two things struck me as very good about their site:

[list=1][*]Their specs are very detailed, down to drive brand, raid model number, etc.[*]Their prices are very reasonable and yet it's clear they are not "too low." [*]They also appear to use quality parts and manufacturers.[/list=1]
Has anybody ever purchased from them? Their site seems high on specs which is always a plus in my book but a good review is worth a lot more.
