so i feel bad that i have been slacking so badly that mr. whistle collector was forced to post ebay whistles in my absence… 
just kidding, but back from hiatus, here are some whistles i found on ebay (small print: not mine, can’t answer questions about them, just hoping people who might not have otherwise got their dream whistle get it this time
as Mr. Collector already mentioned, there are some copelands up for grabs… also a fred rose, although i’ve seen them go cheaper (i got one for about $180, the starting price on this one is $250. still cheaper than the $300 they go for on the irish flute store site…).
otherwise, 2 (perhaps) interesting pvc low whistles:
Merlin Black Knight Low D Pennywhistle Polymer Whistle

–has anyone tried one of these? how do they compare to susatos?
Ralph Cook Low D Whistle
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120573349534&ssPageName=STRK:MEWAX:IT#ht_500wt_1154
–starting bid is $75, no takers yet. also, no photo… buyer beware.
there’s also some water weasels up for grabs, but seem priced a bit high to me ($300).
happy whistling!
