Being new to straights I can say what I thought I would like in a straight I found I did not and what thought I would not like I liked after using a little. So I would recommend getting some more experience before making such a large purchase. I would purchase a TI and see if you like them. Also, items will come up for sale again. By waiting I have found better examples than the first one.
Here's a set for le$$.
