And for those that are curious, Bryan's centerlink is approximately $175 cheaper than SLR's "econo", and around $100 cheaper than L&P's. All 3 are of similiar designs, and will work just as well.
And yeah. TK1 came up with the majority of this idea a long, long time ago, before any of you leaches started making money off it... At least Bryan isn't gouging, and IMO, is offering it at a VERY fair price.
They are very strong, as well. I would know; I had an original "TK1 Centerlink" 5 years ago...
