If you want to see road racing at realistic prices then the southern 100 road races are a must, far cheaper than TT week. They are at castle town on the isle of man 11-14th July, a lot of top names are normally there like lougher, anstey farquar & lindsey. All the races are mass starts & there are sidecars there aswell, it is a real spectacle, night life in Douglas is pretty good aswell. i've got my space on the seacat booked, it falls nicely into the gap in my season
Good web site below for road racing
