I think you will be impressed with the Silky. That's the one I got with the curved blade and large teeth. They only cut on the pull stroke, so I believe the curved blade helps the teeth bite and I like the big teeth since they are aggressive. I second the idea to use a Dremel tool to grind out that hole for your sawblade. It's a lot easier to grind hard steel than drill it.I ordered a Silky pocketboy 130 yesterday.
Couldn't decide on the straight blade or the curved. I ordered the curved which, as far as I can tell, only comes in the version with coarse teeth. It's supposed to be delivered tomorrow.
I also have a Wicked brand saw. It's not bad. But the tip of the blade broke when it got bound during a cut. I ordered a new blade, only to find out the company was bought out and the new blades wouldn't work in my handle because the goof-balls changed the size of the hole for the bolt. Idiots!
