Solar Flare T5 Fixture?

[Tetrarch]

I'm considering buying a used Solar Flare T5 to replace my no-name 175W MH/VHO fixture. It will go over a 95 Gallon wave tank (48"L x 18-23W x 24"H). Does anyone have any experience with this fixture? I understand it overdrives which may decrease bulb life, how often would you recommend replacing bulbs and what kind of PAR could I expect? Right now I can get the fixture for a little under half the price of a 6 bulb 48" ATI Sunpower, does it sound like a good deal?

Thanks for the help.
