PC lighting question...

[TANGOMAN]

It's ironic I come to post the same question and hey, it's already there...
J&L Aquatics seems pretty exspensive in comparison to what's at
www.ahsupply.com AHSupply is American based, on-line, and 55w kits, with reflectors, are $64.99 (U.S.$). Check them out. I've used JLAqu. many times in the past for dry goods and they've been great ! Has anyone shopped ahsupply ?
I'd like to check out Aquariumpros.ca but I'm unclear how to access their site.(my first computer and I'm really illiterate!). I need to download either Netscape or Internet Explorer ? Which one should I download ? I'm using AOL for internet service. Will that make a difference? I wont catch a cold or get a flu bug or a virus or nothin' will I...?
