Well consumer electrics are very cheap (as opposed to to weekend breaks and short holidays). So maybe something like this:
9 Acer 128MB MP3 Players @ €31 each = €279 (see )
3 Creative 512MB MP3 players with Radio @ €90 each = €270 (see )
2 Sony DVD players @ €76 each = €152 (see )
1 Casio digital cameras @ €281 = €281 (see )
1 Philips 23'' LCD TV @ €657 = €657 (see )
2 Nights B&B at the Galway Harbour Hotel for 2 people on 10th/12th September @ €358 = €358 (see [broken link removed])
Thats a total of €1,997 with 17 prizes ranging from cheap (acer mp3 pleyer) to great prizes (philips tv).
