I would not recommend buying one of those so called kits.....I find the materials inferior and useless. First try and decide what flies you would like to try and tie first; once you have decided that go to one or more of the shops...many are sponsors here and get them to help you by making suggestions pertaining to your choice of fly/flies you want to try to tie first . They will suggest what tools you need for getting started.
A vice, bobbin, scissors,bodkin and whip finisher are what I would say are a bare essential minimum for tools. Over tine you'll accumulate more "toys".
If you buy , buy the best quality you can afford....the adage you get what you pay for holds true in this area as it does with everything else.
