these two are well within your budget:
This one is a nice pearl paintjob AB frame with a full Shimano 600 indexed gearing groupset, including the sealed hubs. Only the brake levers are 600 tricolour/Ultegra, from a later date. Mavic MA2 rims, ITM bars, SR stem and seatpost, Gazelle original saddle.
As you can see the bike is in very good condition, paintjob has a couple of damaged places inside chainstay from a slapping chain, and some surface rust near the cable guides that has been retouched.
Seat tube 58cm c-t
Top tube 56cm c-c

apparently my camera went apeshit on low ISO/low light, sorry about that, the colours of the bike as shown the first few photos are correct, there's nothing really purple about it :-/)
