In preparation for new stock coming in about a month, LSK are letting some of their high quality speakers that are still in stock out with a 20% discount.
The M4's are given a positive review on dansdata back in 2002 when they were $200, and Dan is trustworthy when it comes to such things. I've already bought two of them since they only come to ~$103.20 each including shipping.
The rest of the stock is also top notch, practical stuff. It's all kits - you have to build them yourself, but it's fairly easy and all you need is some decent glue.
I can vouch for Dan (from Dansdata) writing quality/trustworthy reviews.
I'm going to buy a set of these.
