Gday Micheal, try Graupner URL for new Roos, and maybe email them for availability? they have been around for a long while now and I hope personally they keep manufacturing them as they are a lot of fun to fly Also theres plenty out there on 2nd hand market if need be! I know of two at least currently up for sale.
Speaking from personal experience the Roo will fly just fine on 12 lb thrust turbines (110- 120 mph) from any sensibly sized sealed strips and will have unlimited vertical performance on engines such as the superb Wren Super Sport (17-18 lb thrust) turbine. If flying the Roo or Rookie from a grass strip I would then suggest an engine such as the Wren SS as minimum thrust! also using larger wheels than stock when flying from grass for less rolling resisitance helps a lot as well, say 3-3.5" diameter.
The Rookie I have not flown but being that the only major design difference over the Roo really is the enclosed engine I do not think you would encounter any problems with the performance off of nice grass strips with an 18 lb thrust engine.... The Composite Roos II's I have built both came in at 14- 14.5 lb AUW dry.
Bottom line is that a lot will really depend on the variables of your flying location i.e. surface conditions, approach/departure obsticals? etc. Also the types of jet models you want to fly later.... this in the end would likely dictate which combo options are really ideal and worth considering....
hope this helps
