I port with a Dremel...
The trick with porting the iron well is to use GOOD burrs and don't port dry. It takes under a minute to start a bridge port with my Dremel, a good mini-burr, and a little bit of water. (Yep, I use water)
No matter what you get, variable speed is a must IMO. It sucks trying to port aluminum with a device that only knows off, and 20,000rpm.

i like the dremel on the irons, it works really well actually. on the rotor housings we've got a 1 speed 20,000 rpm electric, which works, but it sucks....

I'd suggest using a Dremel for porting as well.
I have a Jepson 1/4" electric die grinder which I quite enjoy, but in the past few years I have done all port work with a Dremel and wouldn't go back to the die grinder. The Dremel is just so much more compact and easier to handle.
Here's a demonstration:

Makita long shaft die grinder the best i ever used , lasted 20yrs, using it at least 2-3 times a week, some times on poerting work 2-3hrs at a time .
most grindes go out when not held properly, and it bounces around in the hole, bends the shaft and never good again.
and i have used many die grinders.

the electric one would be nicer if had a couple speeds, really fast = kind of tricky, but i find the dremel doesn't cut the rotor housing very well.

Consider a Foredom. You can get several attachements. The Makita I had sucked *****. The coupler went south, and it was either on or off. I had to get a $150.00 rheostat to make it MORE useful and able to be thottled. I have a Dremel to do the water jackets , but it is waaaay to small to do any serious porting. REally, I don't count the hours it takes to port as productive, but more necesary. I like to get the rough shape fast and easily. I have had great equipment, but have had more value from cheap old Harbor freight air die grinders. I have a compressor on 3 phase so it's cheaper and more controllable to use air. In three and a half years of moderate work I have gone through 1- 1/4" die grinder and I got 4 of them on sale for $4.99 each with a coupon.
The Makita was $127.99 and it lasted 2 years.

i think the hole saw is the right move, actually. so far the ONLY downside to the PP is noise. mine is all corked up, and the power curve is a lot like a stock FD, i could tow with it.
