I've run H/W 60's and 120's which are great speedos, and really good value for money. The V3 is out now, which by all accounts is a great bit of kit, but it's unfair for me tor recommend it as I haven't had a chance to try one yet. I do know the price has gone up, but doesn't it always
On the flip side you may well be able to get some good deals on the 2.1's now
In 4wd I've recently swapped my H/W for an Orion r10 Pro, and I'll back Chris up on this one. They may come out of the same factory and have very similar software but it definitely more drivable and with the same motor I've been able to take all the boost and turbo off yet still go quicker. The JE deal is very good, and TBH the only reason I bought the Orion kit, as the speedo is £££ to start with, and then £60 quid for the programming box is a bit nut.
