looking for a aM/FM sweep generator

[rgbit]

Hello

Good afternoon from Spain.
I'm trying to buy a AM/FM generator, from about 100Khz to 110 Mhz, mainly to play with and adjust my collection of vintage radios. I want one with sweep function, to better adjust the 10.7 FM IF band-pass. I've seen some on sale on ebay, but interesting-but-not-too-good units are rising to stratospheric prices (like some Grundig AS5 ). Some others are a very old valve scratch. And there are some others modern units on singapore or USA, but shipping and customs cost a lot more of the unit itself, like this: http://www.ebay.co.uk/itm/370522784356

Any sugerence about? Somebody want to sell one?

If not, may be I could build my own generator...
