If it was me and your still going for a Linux Enigma2 receiver with Blindscan then the Vu Uno which can be had from Ebay for around £180 is a great choice for a single tuner and if you feel the need to go for 2 feeds in the future £60 buys the Twin tuner Plug & Play module.
Just my personal preference for a VU+ as i feel they have more support than any other receiver and you can use Blackhole image my favourite, Had a TM twin and basically at the moment all TM's Linux E2 models are just basically the same broadcom chipset as what is used in the Vu Duo just with more Nand Flash and Ram memory, Rumour is there are newer models to come out called the TM-2T-Super, TM-Nano-Super etc... which are based on the same chipset as what is used in the current Solo2 and perhaps one model based on the Duo2
