LH Simulations, who develop the amazing LHBP Budapest and LHPR Pér and Bőny, are celebrating their 10 year anniversary with a sale of 50% of their products. They also have a heap of excellent freeware on the website. I highly recommend anything this developer has done, as not only are they outstanding quality, but are available at an amazing price even without the 50% off. You can get the products directly from their website (recommended) or from Simmarket.
