DVD burner that can duplicate Karaoke (CD+G)

I am looking for a good DVD burner that has the capability of creating, duplicating and playing Karaoke (CD+G).

FYI, I am legally entitled to copy these disks. :)

I'm tired of looking at the specifications for each drive and I've hit dead ends because some web pages just don't offer enough technical information specifically relating to CD+G format.

Ideally, I would like to purchase the LG GSA-4163B (http://www.lge.com/catalog/prodmodeldetail?actType=search&page=1&modelCategoryId=CTG1000658&categoryId=CTG1000500&parentId=CTG1000439&modelPrefix=400000&globalCode=GSA-4082B&globalSuffix=000000&model=NOTHING)
but I cannot tell if this unit will work.  

Note: I see that Karaoke is a supported format with the GSA-4163B but is that just reading or can it write to the CD+G specifications as well?

What I require:
- Compatibility with most major formats including: DVD burning, CD+G
- must be an easy to purchase brand and not already obsolete.  Order of preference: LG, Lite-On, HP, Sony, etc..

Also... bonus question (extra 75pts):
Please recommend a good program for duplicating CD+G and creating CD+G media (may be separate programs).

Thank you,
SDC
