I wouldn't say waste of time, the x-wing and tie are nice toys, the landspeeder is a touch pants but it does what is says on the box.
Not sure if you are buying them and want an opinion or looking to sell, but either way you are kinda in the bargain isle on the price front.
If you are starting out collecting the POTF2 is as good a place as any to get in (that isn't vintage), there is a lot of good stuff in that line, Shadows of the Empire being one and given they all come from the mid 90's that makes them almost 20 years old now anyway.
