I bought a DRZ a couple of months ago. There is currently one on ebay starting at £1500. You should be able to get a 2001 to 2003 DRZ 400E which is the one with the more powerful engine and plastic tank for under £1700 road legal with an MOT and not too high a mileage. I understand all the 400E models have electric start. If you want a newer bike then obviously the cost is higher. The SM variants appear to command a higher price, presumably because they have not been off-road.http://cgi.ebay.co.uk/drz400e-drz-400-e ... 574wt_1137
Also have a look at this page where we have been discussing the DRZviewtopic.php?f=59&t=2782
I think I'll be keeping mine for the time-being to see if I can improve my skill and cope with the weight.
