Im after some details, I have LOADS of old magazines and varies things and some 'first issues' that are 17 years old

Anyone know somewhere on the net that specialise in buying/selling this kind of thing? (Ignoring ebay)

What type are they?

Allsorts fella, mainly computer mags i.e gamesmaster

Google and see if you can find forums that specialise in the type of hobbies that your mags cover? From there you can join, sell and I will take 10% for the suggestion!!
