I have had several interactions with Boris Kolomytsev of Kolobob and I have been impressed with him.
The stuff available at his E-Bay store only scratches the surface of what is available.
Visit his website at:

He uses a quality scale of 1-10 with 6-10 covering the majority of figures. Quality doesn't only refer to the quality of painting but to the complexity of painting as well:
6-7 Top Quality
8 About Elite Quality
9 Elite Qual costity (Museum Quality)
10 Elite Quality (Show Winning Quality)
Grenada figures fall into the 6-7 quality range. Eagle is likely in the 5 quality range.
He carries the Russian Vityaz line of figures which are arguably the best in the world but the prices reflect it.
He also carries an exclusive line of figures that in my opinion are of equal quality to Russian Vityaz. It turns out these figures are made for him by Nevskaya Miniatura.
http://www.soldiers-neva.com This is Tatyana Gapchenko's studio. She is a former master of Russian Vityaz studio. These exclusive pieces are about 20% cheaper than Russian Vityaz.
Lastly they do commision painting of miniatures (i.e. Pegaso Models of Italy). I suspect they use Nevskaya Miniatura for this as well since the pricing is similar but I'm not positve
Prices for these figures are exponential. For instance a mounted Samurai at level 8 quality may go for $480. The same figure at level 9 quality may go for $1400-$1800. Level 10 figures demand a premium and the same figure could command $2100. At these prices you are crossing the line from toy soldiers to fine art and they are simply stunning.
That said you can order any of the figures to the level of quality you want.
Here are a few of my recent Samurais
