I posted this over at the primitive archer site just now;
I looked at the fleabay drawknives, there are two Greenlee 10" on the first page, very good drawknives in almost perfect shape. I have an identical one my shop and can attest to it's quality. I prefer a longer blade than 8", I have a 6" that is hard to use for anything other than cleaning up around pin knots.
I like a straight bladed knife, others may like a curved blade. I also like straight handles with no offset to the blade.
What ever configuration you get you can learn to use it.
The top knife is a heavy debarking drawknife and the one I use the most, I like heavy and big.
The next one is the Greenlee
The third is a Pine Knot that is currently on the Trad Gang St Jude Auction, it won't go cheaply.
The last is the 6" swedish drawknife with a thin, light blade. It is hard to keep that thin blade from digging in.
