hmm this looks very good....... A little more than I wanted to spend.
Will look into this, thanks for the link!
thats really the cheapest youll find if you want to suppport SPS.
if you can find a 2nd hand of the older model photon 48. i had one and sps did excellent under it. had great color.
you also can probably get something on ebay similar to the older photon series that isnt programmable to cut out some cost.
