Rog, if you've already built a kit, you know what to expect. I did an Allora 30 years ago and I'm not far off completion of a LB - I can tell you the LB is very comprehensive and great to build. I expect to be on the road by June (it says here...) so that's a 15-month build, same time as Richard (who's mentioned by Guy).
But, as Guy says, you gotta make your own mind up - both kits have their fans! Dunno where in Cheshire you are, but if you want to see mine you might be able to get a look down at the paint shop (in Widnes) if it's in the next couple of weeks...
