A not so cheap(IMO not expensive for what it does) and very reliable alternative would be the Hawkeye Pro, this one is made by Omitec the manufacturer of main dealer's Testbook T4, i've seen one in action and it's pretty remarcable, see this [ame]http://www.bearmach.com/files//HawkeyePro%20Web%20PDF.pdf[/ame] ... i dont have shares in it believe me but i have a simple Hawkeye and i can vouch for it
other variant which i've just seen once working and nice too, cheaper than Hawkeye but not handheld, made by the same company is this http://www.lynx-diagnostics.com/
Discovery Td5 (2000), manual, tuned
