This is the only one in your price range that falls within all your specs in their Signature Ideal selection. However, be warned that sometimes one is told an SI1 is eyeclean, only to find out it's not.
It's hard to recommend from BN, as they give so little info, particularly in the way of Idealscope pics, which were needed for many that I found as potentials. If you were open to other vendors, I could possibly give you a better selection, with confidence.
thanks ellen ! will take a look. i realize BN can be vague. Are there any more from the IDEAL cut section, not necessarily Sig. Ideal? Also, recommendations from other vendors would be appreciated !
