Had my first pint of TTL for ages, a couple of weeks ago. The defining characteristic is the late hopped flavour. You could get the best kit you can and doctor it by adding hops. Not sure what hops Tim Taylors use but you could research that on the forum, then I'd bring the can contents to the boil in the biggest pan I had, and as much water as I dared, and put about half my bag of hops (EKG?) into the liquid when I turned the heat off. After about 20 mins I'd seive the pan contents into my sterilised FV and make it up to volume.
Let it cool to 20C overnight and pitch the yeast. After a week to 10 days when the fermentation has calmed down you chuck the rest of the hops in dry. After 14 days minimum, when fermentation has finished and it has cleared a bit you can bottle or keg. You need 14 days, not the 5 days or whatever they suggest on the kit. The results will be so much better. Time is your friend!
Try to keep it somewhere coolish whilst you are fermenting. Ideally you want it to ferment at 18-20C to avoid funky flavours.
Try the Malt Miller for the hops if you don't have a sourcce locally, by clicking the link at the top of the page.
I was sent a kit ale in the recent Beer Swap. It was very nice!
