Had one of those and the drivers blew out on mine also (and I am very careful). Great sounding but very problematic model unfortunately.
If you can find a used Bergantino AE210 (especially the later vertical model), you would most likely be very happy. Neo, so lightweight, and similar bright voicing with nice low end capability.
Also, a single Genz Benz Neox112 would also give you similar output and a similar punchy, bright tone.
Finally, the Baer ML112 would also appeal to those who dig the NL210... again, loud, tight down low but can handle some bass EQ, and a very present upper midrange.
These 112's are voiced so that the 210 guys should dig them pretty well. Unfortunately, none are priced at the low end.
Edit: Sorry, misread and thought you were looking for a replacement cab. The NL210 is a pretty unusual design with that tuba-like porting, and EA's OEM drivers were pretty goosed (of course, they blew up too!). Not sure about a driver that would sound anything the same in that transmission line design.
