Oxygene is a great long lasting scent - perfect for summer. I didn't think much of it when I first sampled it on my hand, but I was surprised that it was so much better in the actual wearing.
Diesel Plus Plus is a great long lasting ambery fougere scent - very reminiscent of Sculpture to my nose - also good in warmer weather. It is in the same fragrance family as Laguna. (You did mean Diesel Plus Plus in the white bottle correct? Not Diesel Zero Plus in the dark bottle).
Good Life is yet another great long lasting fig leaf scent - a lot of people here who say they like it a lot (me included) find that despite that, we don't wear it all that much.
although the quest is strange (looking for a cheap fragrance itself...) here is the perfect solution:
ADIDAS ORIGINALS by Lancaster is definetly cheap and it smells like DIOR HIGHER. Hopefully you like it. See www.adidas.com/originals for details (you can even send a sample to yourself ;-)
You can't forget Stetson Black as a great scent and cheap too! Don't let the name fool you as it smells NOTHING like the original Stetson. I have a buddy (business guy) who wears this religously and he gets great compliments all the time.
