Like all hobbies, there's always equipment available for all budgets. Since i started looking around on Souq, ACE, Ramy, Speedex, DM, and many others, i've come across utter crap but also pretty decent stuff for an affordable price.
If in doubt, google around a bit or have a look on Youtube. Most decent brands for offroad gear will have reviews about users in SA, Australia, US, or other offroad markets.
Here goes my two cents:
Compressors
Bought two models from Xcessoires (ACE homebrand). The Grunter and Big Grunter if i am not mistaken.They are poorly made but do the job. Recommend to upgrade the hoses and supply wires as these fall apart after using a few times. Imho they cost way too much as these are just rebranded Chinese compressors. You can find the identical ones in DM at half the price. Ended up buying the Camel Brand 160lpm compressor in DM and so far is much better. I don't like using the yellow spiral hoses so i bought separate rubber hoses with pressure gauge. No experience with ARB, VIAIR, Bushranger, or other more high-end brands yet. Although read tons of reviews about them. Like engines, there is no replacement for displacement. The bigger the compressor, the less longer it will have to work, and the cooler it will run.
Ropes
You have a few options here: Either you go for an industrial type of sling which you can find in almost any hardware / general trading shop. This one will get the job done fine as tow rope and also as recovery rope if you are a bit careful. They cannot deal with heavy tugs because they don't stretch.
You should AVOID the 40dhs tow ropes from the gas-stations at any time. They are made to tow a car along the road, NOT for recovery in the desert. They will snap if you sneeze at them.
A very good price/quality KINETIC recovery rope is the AOR brand one. You'll find them in Ramy, Speedex, ACE, etc.. Price is around 370dhs if i am not mistaken. Mind that i mention KINETIC, that means it stretches up to 20% and that recoil builds up massive amounts of energy. I love kinetic ropes but be careful with them.
Shackles
AOR also makes the soft shackles which i highly recommend. Metal shackles will work fine and i also use them if needed, but always carries a bit of risk. Try to get rated ones as they should be better than the cheap ones from DM.
Shovels
Shovels were mentioned a few times before on Carnity. Buy a full size labourer/gardener shovel with wooden handle. I also carry a AOR aluminium one which works fine too. For the offroad drives i take them both along.
It might indeed be good to have a separate thread for buying and selling stuff (like a market-corner).
