For pretty and lots of power go with a Satio 1.00 . To keep cost down, buy a Magnum and paint the head with some semi-gloss black header paint or get the buffer out and polish the Magnum valve cover. For the money , my Magnumshave been very good engines, if I had to buy O.S or Saito's for all my planes I wouldn't build near as much.
Another option , would beto look on RCU market place , I havehad great luck buying used enginesthere. I prefer Saitos , but the retailprice makes them hard to afford with the allowance my wife has me on. I have found the sellers on RCU to be great to deal with and have never been burnt. Just a thought ?
