Most clubs in our area have been running PT's only for some time now as all the handouts are beginning to fail and it's never been a problem. Any new members joining are told that to count laps they must buy a PT, either from the club or from the manufacturer, if they are new to the hobby they don't have to buy one, they just don't count laps until they do. This suits everyone because if they carry on the hobby then they know how much they have to spend on the PT, if they don't carry on then they just sell the stuff they've bought already.
A PT for around £60 is really not that expensive in the scheme of things seeing how much everything else costs. Nowadays you can get a second hand buggy for around £60 (B4), second hand decent speedo and motor for less than £100 and a decent brand new 2.4 radio set for £100, new digital servo for £50, £50 lipo and £20 charger ........... £440 and your up and running with top end gear. You could go RTR even cheaper if you didn't want top end stuff, what can you do these days for under £500? ........ and remember that all this stuff will last a couple of seasons at least no problem if looked after properly
