I'm with you on this one....I paid over $700.00 for my 24" 150w x 1.....and was thrilled....mind you it's still going strong over my 65g hex after 7 years...so I guess it's doing ok. But about 2 months after we bought it, there was a huge price drop and we could've gotten away with paying only what YOU paid!
