I would never cosider buying an enlarger from overseas.
Nor would I .
There's no shortage over here for good as new enlargers , costing little to nothing . I imagine it's the same where you are .
I've bought a few enlargers and have been given some as well , such as my LPL 7700 colour enlarger , for free .
People are just happy to see someone making use of their things again , rather than being thrown away .
I've just picked a 6 feet high wall mounted 5"x4" enlarger up and another Combiplan 5x4 developing tank , all for £50 . The tank's alone tend to sell for more than that .
I realised why it was buyer to collect when I got there and saw it , the photo made it look like a bench mounted unit !
My reply was to post #30 , where it was said India is a big place , so buying one might present a problem .
O.K if you have to pick it up .
It sounds like finding one is the problem the O.P is having , though I'm sure there are plenty for sale still within India .
The link you provided shows they are available .
If they really were that hard to find , for 10x8 print's , the one like that I linked to would solve the problem for very little money .
It's such a basic piece of kit that as long as it is complete there is little to go wrong .
