Sure, why not? $500 seems like a fair price for a nearly unused RS35, although that's about the most I would pay for it. You can try it out and if you feel everything is working like a charm then sell the RS25 for about $300/400.Hi everyone I would like to ask you all for a suggestion. I bought three months ago a pre owned JVC RS25 in excellent condition with the original lamp at 349hrs for only $400. I calibrate it and it looks gorgeous. Now I may get a JVC HD990 pre owned for $500 local and according to the seller basically brand new with original lamp with only 6hrs. All the original equipment except for the lack of the box. Should I try and buy it? I am in love with the RS25 but the idea that the 990 can be even better yet slightly better is very inviting! Thank you!
