			I thought the JBJ's with HQI go for around $300 new, but that is new.  If i was going to spend $500, i would get the LED version new and start fresh.
		
		
	 
 I don't think it's a "great" deal.  Sounds like you might want to build up your own though, which would make a big difference.  I got my 28g JBJ Nano for a steal, you just have to be patient while looking.  Mine didn't come with a stand, which didn't matter for my application, but it would certainly make an impact on my decision process since it comes with one.  The brand new LED JBJ's go for $700 or 800 with a stand.  If you found a 28g JBJ for around $200, and then drop $300 into it, you would have an amazing nano!!  
I have the PC version and have one SPS that has grown like crazy.  I don't even have a good skimmer and only do water changes every 3wks to a month.  In the summer I had to watch the heat very carefully, so in my opinion, I would NEVER go with an HQI version of a JBJ.  Good luck whatever you choose!!
