Well, You could check Ebay Stores, Apexlamps, Lampedia. I have bought there from both but beware with aftermarket bulbs.. Make sure you find the exact Wattage your bulb is as sometimes a projector takes different watts for different models and the sometime sell the wrong wattage bulb..
I for example had some Sharp XR10xl Proj. and they always never sold the correct bulb.. I needed 220w and they always had the 275w bulb fort the other Projector but it was similar in model number..
I would double check the Manual in there they should have the exact model bulb and wattage needed for that projector..
IF you need help let me know I am pretty experienced at bulb buying over the past 3 years I have bought 9 bulbs..
EDIT: I just checked the Mamual your bulb looks to be a UHM-130watt Bulb 1500 lm..
I just checked ebay they had one but quite Spendy:http://www.ebay.com/...=item1e793893d9
I also looked and they did NOT have an Aftermarket bulb for your Specific Model Projector.. I would highly consider looking at a new Projector with the cost of this bulb so high if that would be an option especaially since you may have a problem with the projector which I would say is Probally not the Bulbs problem..
Well I am getting hits on google like this :http://www.provantag...p1~7PANP06X.htm
Just be sure it has the correct Model number and Wattage for your Specific Projector.. I had a couple searches come back and the Specific Projector was NOT listed in there so they must be using a Generic Panasonic search???
