i can only advise what i'd do, and have done
buy top notch LLLL.com, dont get too caught up in cvcv.com
some are great admittedly, but other flavours are out there :D
also NNN.com imo, are a wise investment, domainers still like to lowball for these even though there have been some stonking sales of recent years, outshining LLL.com, also approx 18 times less, and they are truly universal. hold for endusers
for the record i have never bought a sh*t LLL.com, i wish i had nailed a stack when they were $250 on ebay & forums, but felt the same thing then as do now for the worst ones tbh, they may still keep going up, but personally i dont touch them. better to save $15k and try and nail a great one.
the roi on most 'bad' LLL.com is not great imo generally speaking
