Find myself, again, needing a compression tester - have used them, but never bought one.

Would appreciate recommendation on brand, etc - obviously would prefer one that supports various sparkplug sizes vice a specific model for a specific vehicle type. Also, since some engines have plug reach issue, needs to have a long extension to service.

Thanks!
