Looking at Bandit NZ's thread about the prices of TA's in NZ, I looked at the prices we see in the UK. The prices here are kept down by the cost of gas I suspect but may still be higher than the US when you consider $2 to the £ these days.
What I have found however when I have bothered to look at UK eBay auctions for TA's is that they are generally in very poor condition and owned by Jackasses. Words almost fail me in describing just how horrible this is...
Check out some of the questions to the sellor at the bottom.
