Hoping for a little advice...

[lullabymoon]

I was hoping for a little advice about interchangeable circular needle sets as I'm looking to buy but I'm pretty much a novice. I mean I know how they work but I have no idea what constitutes a good connection or the like.

What I'm looking for is a bamboo set, in mm, that's reasonably priced (in the UK) and that perhaps I can add to over time. Does any one have any recommendations or makes to avoid, or any advice in what I should be looking out for?

Thanks in advance.
