Personally I'd advise against it for two reasons, no in fact 3!
1) The economic climate is uncertain
2) Taking on a shop is big responsibility, especially for a novice. The lease can cripple you for starters if things are not going too well.
3) Your choice of product is notorious for low margins and aggressive prices.
If I was you i'd learn the ropes with a much smaller venture, even a hobby. In 2 or 3 years once you are established, up and running and know the ins and outs, you can then look at retail.
