I have done a lot of work on the PIC24F series using MikroElektronika dsPIC Basic compiler, and have had no issues with Interrupt or having to implement a DT_INT style system. Interrupts are handed well in the compiler, which I think is due to the way the improved architecture handles them. One you try the Peripheral Pin mapping in the 24 series its hard to go back !

The only issue I had was changing my coding style after years of working with PBP ! I still use PBP for all my 16F and 18F stuff, so don't shoot me down for promoting other peoples products !
