If it's all in good shape and the stand and all is nice I would for sure go look at it. If it's a coralife light then its a bit cheaper than the aquatic life one and they usually are CF
fixtures so make sure you check that out.
$220 is kinda cutting it close as far as value. I've found the hardest part of my builds is always the stand. lol Especially for a 29g, lots of stands come in 24" and 36" and up but the 30" ones are kinda hard to come by near me.
In the end, it's what you think. When you see it if it's worth the money to YOU then it's a good deal.
