will a 13 3/8 x 19P RH prop work for my alpha one? Now somebody suggested that everybody goes for just the pitch these days. I had a 14 x 19 aluminum before but I want to upgrade to a SS ballistic and the size is 13 3/8 x 19 for a great price. will the difference mess my engine up?

It will fit, but you may not get the best preformance out of it. Your RPM's should be fine, the change in diamiter will increase your rpms, and the change to Stainless should reduce them a bit and they should almost balance out. But it is really made for a smaller motor. What motor do you have. If it is a larger one I would think about looking for a larger blade.

What price is a great deal?

Remember, designs can be produced with SS that cannot be done with aluminum. In this case, based on my data, you should see slightly less RPM on top. you should be able to maintain hole-shot as the Ballistic is vented, however, this particular prop is known to vent at lower trim angles than even some aluminum props.
There are much higher tech props out there for less money.
