Agree with @ProDomanico - It's a good name and definitely brandable, but I find .net dictionary words difficult to appraise.
The extension obviously dilutes the value somewhat, but the fact that dynamize.com is undeveloped means you may have a little luck finding an end-user unwilling to pay top dollar for the .com with an opportunity to brand on the .net with no current .com competitor.
I have a few dictionary .nets myself, but don't mind admitting I find them difficult to price accordingly. Taking a semi-educated guess, I'd say high $xx-low $xxx for reseller, mid $xxx-high $xxx end-user.
