Alon II MK2 vs Thiel 2.3: Best Value "Used"??

First,I need some input on the Alon series, in particular Alon II MK2 which retailed for $3000. Second, has anyone ever heard and compared the Alon II against Thiel 2.3.?? What is Alon like in terms of bass and soundstaging?? I have never heard them, but have heard the Thiels. I think the Alon II Mk2 was "upgraded" to the MK2 and issued about the same time the Thiel 2.3 came on the market, approx 1999. Though the Thiel drivers were upgraded in June 2001. All opinions welcomed. Thanks, SJ
