I'm selling a 2001 curved 32" on ebay as we speak. But I've had all the different types at one stage or another.
The RF 32 with DVD is a cracking tv and if you can afford it, i would go for that one. The prices of all avants are coming down all the time as the market is flooded by people chopping them in for a new BV7 or 9. Peters price is bang on.
Youve then got the RF 32 with a VCR. These go for around 900-1200.
Then the curved 32's can be anywhere from 400-800.
28's are normally worth approx 75% of the value of a 32"
The early ones from the mid to late nineties are notorious for dodgey tubes and should be avoided, especially as you can get a newish curved one for a similar price.
The colour also makes a big difference. Black costs the most, then silver, then the rest ending with lime green. Yuck!!
The age of the set doesnt really matter. Its more about what type and colour you go for.
