Replacement a Grace 707 arm

Any suggestions/recommendations on replacing of Grace 707 arm mounted on Luxman PD-121 TT with resonably priced arm ?
Don't know what's reasonable for you, but there's an hour left on this auction:

I replaced a Grace 707 with a Rega arm and was very happy with the results. The grace is quite dated and the Rega's are a good value for the $$$.
