I have 2 Boye sets. I love them! I know these sets can get quite expensive, so do what I did.... get them at 50% off!!!! Go to JoAnn.com. I believe I get a 50% coupon from them every month. That way your $70 set only ends up costing you $35 (+/-). I've had mine for about a year now and I can't say that I've had any problems with them at all. I love how I can make a cable needle as long or as short as I need to. the plus side of having 2 sets, especially when sock knitting, you can use 2 circ. instead of 4-6 dpns. Anyway, just thought I'd send you in JoAnn's direction. Sign up for the free newsletters and you'll start seeing all the discount coupons.
I am going to look for myself. If I return before I get back, keep me here.
