I know it will not help you, but in case, I just completed (two days back)
building a (hefty) bench top power supply: +-1.5v to
+-32.5v, 3Amp, regulated (LM350 (3Amp version of
LM317)). I should have had done this long long back, but
was lazy so far. If you need the PCB design then let me
know I will post the pdf of the actual size PCB.

Have you visited Bhendi Bazaar anytime.
Not for Mumbai, but if you travel to Gujarat and are near to Alang, go there. Many things removed from the ships are sold there.

Photo resist film method is very easy and time saving method for making professional grade PCB (you will need good quality copper Laminate) 1.6mm laminate is best to start.
Also it is cheap to use.
Send me a pm with complete postal address I will send some film.
All you will need is a small UV box with at east 8" 0r 10" uv lights.
Dark room and some patience.
Hi Viki!
I am sure there are people who will be interested
in your offer. I am quite happy with toner transfer method.
Roushon.
You have mastered the toner transfer method, so you can make pcbs with less efforts, But all this has happened after spending considerable amount of time, effort and money to reach a working conclusion not counting the no of miles you would have traveled searching.
If it is fine with members here I would suggest a group buy giving complete solution. Pcb-Photoresist film-Developer-Etchant.
It will save many diyers time and money.
One of the main concern with photoresist is,it has an expiry date which is 6 month from manufacturing I guess.
I bought my scope from bangalore,A preused Tek2465 approx Rs.35k.

Shelf life is 6 months. But if stored properly under 23degrees it longs about 2 years.
Its here both electric and hand drill:
Tools & Hardware
But I would suggest to look at your local market for a
cheaper alternative.
Edit: Just noticed Mahesh pointed to the same source.

You can get hand drill for Rs. 80 to 90.
An externally hosted image should be here but it was not working when we last tested it.
I recommend you buy a rotary tool you can get a chinese one for Rs 2200(Lohar chawal) full set with flex shaft. You can cut copper clad and use it for a lot of other things.
Drill bits for pcb cost Rs.10 in Visha an Rs.5 in Lohar Chawal

Dremel is a brand they are quite expensive but really good quality rotary tool you can get it from flipkart.com or snapdeal.com
The distributor in Lohar chawal quoted a high price
