is the Real Ghostbusters DVD complete series really missing episodes?

[LoneWolfCub]

im not sure where this goes.....but are there really episodes missing from the complete Real Ghostbusters series on DVD? wal mart has them in store for 30 but of course cheaper on ebay. and i was thinking about picking them up. but i also heard the firehouse set that came with the steelbooks, had all the complete episodes. the steelbooks by time life was also released seperatly. as individuals. the same set from the fire house set. and their dirt cheap when you find them online. sometimes. but the problem is. you cant find them. i had vol. 1 couldnt afford the rest of the set when they first came out. bc i think i was still in high school when they came out. or a few yrs after high school
