bucknutz, i have investigated this a bit as i have been looking at buying an inflatable at some stage. at the moment i am using a friend's intext sea hawk II (around R2000 at sportmans/outdoor warehouse). you can get a bracket for a motor for R300. the boat seems pretty sturdy and the materials look fairly durable. intex also makes a 4man boat, called a mariner (around R3300). it uses the same bracket for motor. these boats have inflated floors, so its not easy to stand and fish, definitely not possible with two people on board, unless you make some mods. one of the sealine members have modified a mariner, i think it might be LGF?
i am looking at buying a famous when i do buy a boat. the 3.4m famous is priced at about R4500, with the 3m going for around R4000. at that price difference i would definitely go for the 3.4m. the famous has a hard bottom from what i gather, which makes it easy to stand and fish. you also do not need to get a motor mount bracket.
you can also look at the ark range, if your budget allows it. i have heard and read alot of good things on the ark fishduc 2.
but at more than R6000, i would rather go for the famous.
this is my very personal opinion, i am not an expert on inflatables.
as for the motor, i got a minn kota endura 40lb trolling motor for R2600 from tackletogo in centurion. 105Ah battery and charger cost me around R2000 from current automation in jhb.
