Who cares if they service them? For the price they sell for used, just buy another if it quits working.
I'm sure the Digipro F is nice, but it's also $289 from B&H, probably more most other places. I paid $63 on eBay for my SBC complete with 15/7 degree angle attachment.
That's not a reason not to prefer the digital if you want to spend the money of course. It just depends on what you value and what it's worth to you.
