Best budget wireless tkl

[PastryPerson]

I have been looking for a budget keyboard and the features I want are
Wireless
RGB (software good but not required)
TKL
Mechanical
(hot swappable would be nice but I don't think I can get that at this budget)
Compact
Less then A$90
Im looking at the RK G87 but also have seen an RK sink 87g but am unsure if it's real and what the differences are, if the only difference is the bulky RGB base I would prefer the sink 87g. If any other keyboards are available it would be great if you could let me know.
