I started with a saw from Canadian Tire. It was great, for a while....got the missing screws to use pinless blades, but that is not what the saw was designed for and they never worked right.
Used the deWalt saws at Lee Valley courses. A definite step up from the CTC unit, but didn't feel quite right.....
Picked up a used Excalibur EX-21 for a bit less than the price of a new deWalt, and have been very happy since!
Except for when I was trying to get a couple of items finished for our yard sale, and the lower chuck had a problem. Ordered the Pegus chucks, but they didn't get here in time, so I put them on the following week. Definite improvement! May be personal taste, but I will echo Don's feeling about how the Excalibur design works.
