I am joining the Derails Fan Club, which I see is well represented here. I needed Peco points ST-240 and 244. 240 was out of stock at many of the usual places, 244 was more readily available. Amazon produced the highest prices for both, Ebay not much better. Continued searching led me to Derails who not only had both in stock but also shipped post free. Ordered on Monday, delivered on Wednesday. Excellent service, including an email reply on Saturday night. Well done to them.
Note to self: Check Derails site first.
