Reply to Need some virtual vinyl advice

Hi all,

First post and all that. I'm hoping I can get some advice on virtual vinyl systems. I had a go on one a while back briefly while drunk, and for the the first two tunes I didn't actually realise that it was a virtual vinyl system, I'm sure the drink helped but that was a pretty convincing demonstration, admittedly I had no idea such a concept even existed, but since then I've been giving it some serious consideration. I gave up DJing when vinyl decks started getting replaced by CD decks, but this whole idea gives the best of every world and the potential alone is inspiring. Also I've been asked to start DJing at a chillout session here in Doha - my musical weapon of choice these days.

Anyway, I've just looked at Numark's system and it sounded awesome until I read the reviews on Amazon. So, in short I a few questions to fire off.

1. Does a really good virtual vinyl system exist and who makes it?
2. How often would I have to replace the timecode vinyls?
3. Will they work with my 15 year old 1210s which have been lovingly looked after although somewhat forgotten and currently living in another country? I've no reason to believe not looking at the way virtual vinyl works, but it doesn't hurt to check.
4. Are there any pitfalls before I start looking to invest in one?

Thanks in advance for any help or advice.
