About a year ago, I almost ordered from THE ZEB as welll, but after reading many opinions about how they suck the big one, and getting many emails from folks verifying the same, I didn't order from them.
A snazzy website can be misleading...it almost got me. I love lots of detailed pics of electronic components. They had a lot, and they almost had my money too.
Sounddomain.com is a good place to buy car audio gear from. I will tell you this:
1. They have excellent prices
2. They are an internet reseller: i.e. they have NO stock on anything: you order, they order, then ship it to you.
3. Their customer service sucks
4. They did not rip me off at all: I got what I ordered, in fine shape, for an excellent price
5. Expect to wait anywhere from 2 to 4 weeks after you order to receive you shipment
6. You will need to nag them as to the status of your order: they have your money, they are in no rush to fill your order
7. Please see numbers 1 thru 6
And there you have it, my friend. As brutally honest as it gets.
