4sevens lights are not actually "budget" lights, but some of them are pretty cheap until november 26th
Remember they are very good quality lights, and they come with holster, lanyard, batteries and international free shipping. They are even cheaper if you use the coupon CPF8 (-8%)
These are my favourites (remember to add the coupon to get the final price)
Preon 2 (red) 31 USD
Preon 1 (black and blue) 27,2 USD
Quark Mini AA2 29 USD
Quark Mini AA 33 USD
Quark AA (46 USD) This one has moonmode, and i bought it a week ago for 52 ¬¬
All of them here
