From my little birdie...
BG250-115 MAP $399
BG250-210 MAP $459
BG250-208 MAP $499 (MSRP $750)
When the TCE rep posted here that the US price would be $499 for the 208, I didn't think the company would address MAP prices...wrong, yet again.
There don't appear to be final price lists distributed, so I suppose there could be changes.
IMO, that difference between the 115 and 210 is a pricing fail. They sound slightly different, and it's a difference where anyone might find either one preferable.
Since the BH250 isn't detachable from the 208, IMVHO, that is a design and pricing fail. A latch and pegs instead of screws/bolts would have been all that was necessary to make that happen. Not being detachable, I see it as the lowest rung on the BG250 ladder. Extension cab support? Meh...that's not a high value feature to me. I think "primary use" is the main consideration. I don't see buying a combo with primary use being with an extension cabinet...if that's the case, why buy a combo? Trying to (personally) envision the utility of the 208 in terms of extension cabinet use, I have great difficulty not seeing it essentially becoming a 25lb BH250.
