Off-the-peg Alloy Wheels

I'm doing another Rapha (Prestige) ride that involves gravel - this time 200k in the Ardennes. They strongly advise against carbon wheels so I'm looking for some good value alloy wheels to fit to the Foil that are robust, none-too-heavy and won't break the bank. I've seen what's mentioned in the bargains thread. Any (other) thoughts? They won't get much use and will probably end up on #2 son's road bike.

Anyway, a man of your stature (moral of course
Not very cheap, as handbuilts go, but deffo off-the-peg!
Otherwise get some Fulcrum 7 and cross your fingers
There are some cheap Shimano wheels that often get mentioned, can't remember which ones though.
Marin Nail Trail
Cotic Solaris
Shimano WH-R501. Bombproof and you can usually get a pair for about £60 if you shop around.
PX Kaffenback 2 = Work Horse
B-Twin Alur 700 = Sundays and Hills
It's that I don't have any time to organise some proper ones - I just need them to turn up in Amsterdam in the next couple of weeks.
Thanks for the suggestions - I'll take a look.
I'm assuming you are after wheels with discs. I have a set of those shimano ones a couple of rungs up and yes, they are very good.
