We describe the results of a high-statistics simulation of the SU(2) Higgs model at λ=∞, β=2.4, 2.7 and 3.0, on lattices of sizes ranging between 83×16 and 143×28. The measured quantities are the Higgs and W masses, the potential between two static sources from which the renormalized gauge coupling is extracted, and the vacuum overlap order parameter which defines the Higgs expectation value in a gauge invariant way. Strong finite-size effects are observed. They seem to come under control for the larger lattices, at least at β=2.7. Renormalized tree level relations are found to hold remarkably well at β=2.7 and 3.0.
