Say you have a compact scope for visual but no mount, here's a bargain from Teleskop Service:
An AZ-3 mount-and-tripod combo for 65€ is unheard of, it's an even better deal than when I bought mine for 69€ at the end of 2012. Most other stores sell it between 100€ and 120€. It's serviceable as is, but if you're a tinkerer and like real smooth gear, it's easy to strip the thing down, look for little burrs (you might find none), and sand or file them down.
Clean it, reassemble it, and lube it. Since these are always lubed too heavily with a pasty grease, remove those large blobs of extra grease before you deburr it. After reassembly lube it with the grease you'll have set aside, that's it.
Now say you have a bigger scope, and prefer an equatorial mount, there's another bargain from TS:
It's only an EQ-5 equatorial head but it's only 172€; the tripod is easy to build with thick wood. Or simply attach the head to a permanent pier, and a substantial scope (between 8 and 10 kilos depending on tube length) can be driven equatorially for really little money.
