I've used this from dipmicro.com without any problem:

http://dipmicro.com/store/XC4-32768

The load capacitance is 12.5pF. The effective serial resistance is not given though. And it's out of stock.

Thanx u guys :) appreciate the help but ordering such a small thing online is very expensive :( Lemme try a few other local shops here :)

You in USA by any chance?

nope. All the way in India. Here price of the crystal in the shop is half of what is given in the link u gave just now  ;)

I was about to offer you one for free if you're within USA, in a tiny envelop.  ;)

I guess a local shop is better option for you.

Exactly.. Here each crystal cost around Rs. 4. That's like less than 0.1$  :) If no crystal here works I guess i got to order from somewhere :(

Just post here or on bars forum asking for good shops (online or local) in India. Lots of friends in India visit this forum and should be able to point you to places for parts.

Once again Thank you all for your help.. :)

PLEASE mark this Subject [SOLVED] when you figure this one out!

I keep thinking about it, even riding the bike tonight.

I'm about 4:1 it's the crystal characteristics. 

You have the primary Engineering requirement: persistence.

Have you tried salvaging a crystal from an old watch - don't know what their frequency is but they are free

Yippee! got it working... I bought a new crystal from another local shop, its working nicely... Tried around 12 crystals for the entire project though and the 12th one worked  :D I think the stuff I bought from the earlier shop was from a bad stock or something ... Phew! What a relief...
Thanx again for everyone's support... :D

Glad you finally got it working. Maybe you can start a list of good shops and bad shops and share with local electronics fans ;) I don't have any shops near me except the RadioShack. I go there for replacement soldering iron tips. Man, they got me hooked when I bought their cheap iron. The tip is too fragile. Maybe not thick enough tin/chromium + too much power.

That shop is usually good.. :) This might have been a really rotten stock :D
