Talent have quite a few bats kicking around in the back of the shop, they have their own brand of Talent bats as well which are decent.
The Custom Bats are made by Hunts and they sometimes have a couple kicking around, they're cheaper because they have no stickers and are good bats. I've bought 2 from there and they've been good quality. They don't mind if you take your time picking stuff, I once spent 2 hours in there chatting and only bought an anti-scuff but I play cricket with Paul who runs it and he knows what I'm like.
Owzat is a bit farther for me up the motorway, 15 mins to Talent or 30 to Owzat. I haven't been ther for a while but they have a good selection of kit and they always have the clothes I want in my size which is nice. I did buy the best bat I've ever owned from there (GN Megadrive) so going on that I would recommend them.
It really depends on your brand preference or what you are looking to buy? both shops are helpful and a phone call to them for a quick chat might help your choice.
The B&Q near to Talent has a breakfast van which sells the most delicious Sausage cobs if that helps.
