Ebay has to be the place to start -
I bought a French horn for £80 in UK and it was worth at least £700
you can find them at walmart or target for really good prices :]
You can play alot of notes! they range from like a really low g to really high c that is 2 lines above the staff. i know this b/c i play the trumpet and take lessons.
Good luck... Most good condition used Bach Strads will run you between $750 and $1,000 or more. Your best bet would be on eBay, but be cautious... some sellers are not very honest. You should always play a trumpet in person to make sure it's the right trumpet for you.
There are a number of places one can find a GPS for an affordable price. It really just depends on what features you want. I would recommend Best Buy, Amazon, and EBay.
You can look on Amazon for CR1225 batteries. You can also look at your local stores for these batteries. Amazon often has low price batteries. It is really important to find a good quality battery though.
