I don't mean to sell you into a financially bad decision. If $90 is more than you can justify. Sometimes it is better to start off with something lesser and upgrade later at a better time financially - even if it means tossing a $30 - $40 tool and $20 - $40 in belts.
Consider your current finances as well vs. maybe a different ability in the future vs. ability to invest in a better tool now.
I can't rationalize all factors for you. Just making some "General" arguements.
I metioned before, I do lots of projects, woodworking and stuff.
For me, the end result is what I mostly want, but one of the "Joys" of working on projects is the work itself. Good tools can make a big difference in the enjoyment of the project and possibly the desire to do "MORE" projects.
A relative comparison: I am sure you had cheap knives before you understood and appreciated nicer knives. Now that you understand and appreciate nicer knives (tools) you tend to "Enjoy" using the nicer ones more than the cheap ones... ?????
There can be more things to appreciate in quality... to a point.
I feel for most people, the SA180 will hit the sweet balance spot for investment vs. return.
For most people, you either have to have much more expendable income, a serious hobbiest or making significant return in profits on your investment to justify the next steps above the SA180. Again, the Grizzly is almost $500 delivered.
The Kalamazoo is nice. But, I am not sure it is much better for most people than the SA180 and the Kalamazoo is about $230 + Shipping = probably close to $300 shipped!
The 30" models can do a lot. But, there is going to be a very noticable difference for most people in the upgrade.
In any event, again, consider your personal finances vs. the investment. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
