Nah, its going to be rings, im in the middle of doing one at the moment, DONT get another engine off ebay unless you personally see it running, as people sell them as "running engines" doesnt mean its not a smoking engine! If you wanted to swap the engine, look for another MK4 engine, loom ecu and immob unit. Gearbox iirc is 020 type on the 1.4 unlike the MK3 which was diffrent to the tall block engines so your gearbox should fit the 1.6 and 2.0l engines etc.. a good engine will set you back the price of rings, especially if you have some one who can do it mates rates labour wise. Might be worth looking into having them done. £600-800 ish i would expect to pay at a garage, im doing some at the moment for a freind for £420. Couldnt get a *good* engine for that.
