...for the price, considering these cost ten times more when new it isn't too bad, keep in mind the seller is guaranteeing them to work, and will accept a return 15 days after the purchase date, also if need be they will RMA it.
I am not in anyway shape or form connected to these guys, so keep that in mind!
Anyone that buys these split systems will have no problem dropping a few grand to get brand new tubes for them! (...actually they have probably already initiated the buy so that once they get this beast they can just exchange the tubes)
...at least that is how i would do it!
that being said the difference between a well setup 8 inch LC and 9 inch LC is in the few percentile! ...so if someone is after a decent buy there is a brand new LC 8500 on ebay that I have been eye balling for a few weeks!
...this setup with a decent video chain is pretty hard to beat at these prices, well short of spending a few times more the money!
Anyhow good luck
