Welcome to LumberJocks!
Have rebuilt several different brands & models of 15" planers in past. IME - The old models are ALL the same. There are very slight differences between the Taiwan and Chinese made models, but they are still basically the same.
Taiwan released a new cost reduced design of antique 4 four post planers; Grizzly sells it as G0890/G0891 models and Jet has similar version. It has much lighter head, lower overall mass, and fixed tables, which is nice when using feed extension tables in small shop.
None of the 15" planers I have seen have an internal chip blower.
IMHO - if your shop dust collection is not adequate for a planer, that is different problem to solve.
What is wrong with current 15" ShopFox planer?
(Post some pictures, maybe I can help?)
The Taiwan 4 post planers are hard to kill, easy to fix, and parts are easy find. I would be trying hard to repair it; before considering a replacement. Some repair examples?
One can completely replace EVERY bearing (~22 if memory serves me), both oil seals, belts, with new gear box gasket and oil; for well less than $200. A new rubber out feed roller even with today's inflation is only $115 at Grizzly ATM. Couple of abused machines I rebuilt had broken speed change levers that leaked oil; and those can be fixed for less than $75 in parts. Add a new set of T1 steel blades, and you have brand planer that can run for another couple of decades.
Bottom line: It is rare that a mechanically inclined person can not put a 15" planer back in service for well less than $400, unless you need a new motor. Even with a new motor, rebuild costs are well less than half the current new machine price.
PS - Where is community shop located approximately?
If nearby, I could likely be convinced to advise/assist with ShopFox repair for gas money.
Which is good reason to put your approximate location in your profile.
Cheers!
