I normaly advise when possible to buy in local Irish outlets, but I got a great deal on ebay for the soil test kit I got.

www.thenurseries.com - Preston Bisset Nursaries in England do a great deal on a kit I got via their ebay shop - http://stores.ebay.co.uk/Preston-Bissett-Nurseries - but you can also order them direct

A Westminster test kit will give you approx. 30 tests - more than enough for 2-3 years for me, and thats a fairly large kitchen garden.
It only cost £5.95 + £2.25 postage.
That is a real bargain, its very easy and simple to use, giving accurate results.
I looked at electronic soil testers, but for the affordable ones the reviews were poor, so it is this kit I would recommend.
