I have tried the ACS T1 and T2 before, though they aren't mine so clearly the fit isn't going to be 100% perfect. If anyone is actually interested to know I could post some short impressions, though i don't think my impressions would be very accurate or reflective since they aren't mine in the first place.
Yeah I totally agree with that. The cost of customs is just too prohibitive. I could think of quite a bit of home gear that would go for that kind of prices.
As it is, I'm very happy with my ER-4's, and I'm stopping at that.
