The pcv head units are getting old now so repair or replacement could be an expensive process.
Integrating the pcv power data with GPS from your garmin is practically impossible
You may have compatibility issues with your computer if you're a Mac or on Linux.
If none of these issues matter then go for it.
I noticed the seller didn't include a HRM. Guess I will have to call SRM tomorrow to see whether there are compatible HRM's. Otherwise, I guess I would have to run Heart Rate and Power on two separate computers.
-PCV sync up with PC perfectly. I use Mac and runs VMWare Fusion+Windows and downloading has never been a problem. You just need to download and install free firmware from SRM.
-The cost of getting wired and wireless system serviced @ SRM service center the is exactly the same. The service center has plenty of parts to keep the unit going for a long time.
-Wired is somehow more reliable than wireless. Somehow wireless version is little finicky.

depends on the model of PCV - some work with old style analog HRMs afaik. i think they're differentiated by a mark on the back (not sure exactly, i just recall reading something along these lines here or on wattage/st/rbr or somewhere like that). if you need a new PCV they come up from time to time on fleabay for USD200-300 or can be had new direct from SRM or from places like cyclepowermeters for USD700 (i think). if you needed one desperately then you could always buy a complete system from fleabay for USD500ish and then sell the crank only or keep some spares.
overall, i think it's still quite a viable option - i run a quarq on my roadie because i want GPS data and garmin integration (basically, i love playing strava, there's no other reason to have it in all honesty) but i use a wired SRM Professional on my track bike which is about 10 years old and it still works fine.

Would be good if they were. But I think it was the other way around - the first wireless cranks could use a wired pick up and PCV...
Other than price, the best thing about the wired SRM is it's reliability. It never fails. There is no data corruption or loss and it is pretty much invulnerable to normal environmental conditions. The bad thing about the wired SRM is the battery life of the PCV. As compared to the PCIV, it sucks. The new replacement battery is better, but it still isn't as good as the old PCIV and not like the PC7. The solution is to store it on the charger, but I always forget.
You can set-up a wired SRM almost as cleanly as a wireless SRM. Even when the wireless SRM was available, for the first couple of years, certain of my friends at Team Highroad ran the wired SRM because it was so reliable. Don't be afraid of the wires...
