I purchased this DynaJet AT-200 on eBay. I already had a used AT-200 and for some forgotten reason I bought another. The seller was offering a new, unused PC+AT pair for a Yamaha but didn't get any bids. I asked if he would offer the AT-200 standalone and when he did I purchased it for $200.
WRT your cost, I will put the AT-200 up for donation sale. When you receive it, you decide how much it is worth to you and send that amount as a donation to the CMW forum. Ask Brother Rhett how to make your donation. I will pay shipping assuming it is not over $50.
Gizzo has first refusal, then Jako. If neither member purchases it by mid-July then it's available to all.
