These consistently sell for more than they ever retailed for. No amount of communication to AI ever seems to convince them of the amount of money they are losing by not continuing to offer a legacy version.
$5100 for a non folder AE Mk2? When did AE prices go crazy?
I bought one of my AE Mk3 folders new from Mile High for about $4250 and the other one used from the PX here for about $3600. Sold them both for $3500 or so when I upgraded to ATs, but that was quite a few years ago now.
Soon after the AT was released (at a much lower price than the AW) I remember watching quite a few AEs selling in the PX in the high $2k range, and at least one without a barrel in the low $2k range...
