A Surefire 620V, 952V 720V are all great options for IR and white light. If you don't need to engage past 100 yards at night than these work great. I have a 952V and a 720V and the extra IR output of the 720V (240mW vs 120mW) makes a noticeable difference at greater distances.
For an affordable setup I recommend picking up a used 952V for around $200-$250 on the EE, and run that with an LDI Class 1 OTAL or ITAL (depending on where you need to mount it) IR laser. This puts you in the $700 range for a great white light/IR light and IR laser setup. The DBAL D2 (cheaper red version) goes for $1,485 so you could have two rifles equipped as I mentioned for the same price. Also, the battery life on the D2 when using the illuminator is just around an hour, where the Vampire light from Surefire give you 8 hours or better.
I am not saying that the D2 isn't an awesome unit, but it is important to asses your personal needs and go from there. For lighting up a target from several hundred meters, you cant beat illuminators like the D2, SPIR, or TNVC's tourch.
EDIT: MIssed the no helmet part
If you don't plan on ever using a head mounted NOD setup, the IR laser is of little/no use. That said, most prefer running a head mounted monocular aith an IR laser as an all around better do everything option. Again, your personal needs may dictate otherwise.
