Older Tom Toms - any good

[mcflurry]

There are few TT700 and TT710 models for sale on ebay and return stores for "special bargain prices".

In their day they were decent models, and usually include full euro maps etc. One company has the TT710 for £99 + VAT for example, so about £20 cheaper than a TTOne UK only model.

Are they worth buying (depending on price etc) over a newer TT One?

Cheers - do you know if the maps are any different, or whether TT would supply an update when the box is registered?

Thanks in advance
