Derbies? Boots? Size? color? material? requirements (heel height, shaft height, point/round toe)? new/used?
New for that price is hard. Drop lower in price and buttero is your best option. A little higher, and guidi is your best option.
If you okay with used (even just slightly used), then you can find guidi, carpe diem, layer-0, and now MA+ for around that price. On the previous page I listed a lot of offerings on Ebay that you might want to check out.
